LOCKING APIARATUS F011. VACUUM FUEL SYSTEM...

n Y To ad! wom may concerm; i

Be it known that I, SMUEL Premian,-

a citizen of the United States, and a resident ""'of Cleveland,` county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Locking Apparatus for Vacuum vFuel Systems, of which the following' is a specification, the principleof the invention being herein explained and the best lo mode in which I have contemplated applying that principle,4 so as to distinguish it from other inventions.

The subject of the present invention is the provision of locking means suitable for use with vacuum fuel systems, such as are commonly employed on automobiles. The device consists of means for releasing the vacuum' on the small tank and of otherv means for locking the fuel lines prevent- 'ing flow of gasolcne from the vacuum'tank to the carburetor. To the accomplishment of the foregoing and related ends, said inventin, then, consistsof the means hereinafter fully described and particularly pointed out in the claims. The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one V of the various mechanical forms in which the principle of the invention may be used.

In said annexed drawings z- Figure 1 is a diagrammatic layout of the device with parts in section, showing it conneeted to a vacuum system; Fig. 2 is a section through the vacuum line lock; Fig. 3

is asimilar section but showing the lock in a second position; Fig. 4 is a section on the liie 4 4, Fig. 2; and' Figs. 5 vand 6 are diagrammatic layouts of modified forms of the device. n A

. The present invention consists of a suit-V able lock 1 which consists of a easingr 2 having a key actuated Valve 3, the casing bev ing s'iown as mounted in the cowl board 4.

of avehicle. The valve 3 is provided with an aperture 5 adapted to register with two, ports 6 and 7 in the casing, and the .valvei also has two cutaway p rtions 8 which are connected to a conduit?) in the bottom of the valve casing` the conduit exhausting to l the atmosphere through a series of apertures l, 10 as best shown in Fig. 3. Y

The usual lsuction line 11 of a vacuum system is connected to the engine manifold l2 and then leeds to one port 6 of the lock,

the opposite port 7 being in communication through a pipe` 13 to a 'second valve casing. 14. This v alve casing is shown as mounted on the Idash board 15 of the vehicle and has 60 a piston valve 16 mounted therein. The

. suction line 13 entersfthe top of the easing.

and by means of a by-pass 17 is connected to 'an outlet port 18 which is in turn incommunication )with .the vacuum tank 19 65 through the line 20.

At the middle of the casing, themain gasolene feed ligne 2l is connected and is,l in the normal position of the valve, open to a fuel line 22 leadingl vto the vacuum tank. 'I0 The fuel line 23 from the lower part of the vacuum-tank is connected to the bottom prtion of the valve easing and leads out through a pipe-24 tothe carburetor. A

vent port 30 allows the -'gasolene to return to 75 the vacuum tankso that thepiston valve may close.

Within the easing as beforefmentioned is afpiston V"valve` 16 formed with three full-sized portions 25, 26 and 27, con- 80 nected by smallerportions 28,A the lowest lportion 27 having a 'cone shapedlvalve 29 closing. the outlet pipe 24 when the'f valve is in itsdown position. In the normal running position shown in Eig. 1, the suction line 13 by-passes around the upper valve part 25 and then leads to the vacuum tank. The gasolene from the main tank passes below the-intermediate valve part 26 and out to the vacuum tank. The carbureter fuel line passes below the lower valve 4part 27 and -out through -thel 1ine.24 to the carbureter. i A

The piston valve is automatic in its operation. When the valve dropsLall the ports are closed and the suction created at the top' of the casing .raisesjthe valve and allows the suction line to be opened to the vacuum tank thus' awing the gasolene into., the same fr the main tank.: 10o

When it is desired to lock the car, the key lock is turned to 'the position shown in Fig. 3 venting the incoming suction line 6 and also the outgoing suctlon line 7 leading to the-valve casing/.through theapertures 10. This allows the piston valve to drop,\ which closes the main gasolene line to the vacuum tank, as well as the linefrom'the vacuum tank to the carbureter'. As nof suction can be placed onthe valve easing, the piston 119 valve will rel ain in this osition4 until the key valve is again turn to' the position shown'vinFig. 2, when'the suction line is closedl through the key 'valve to the valve casing,"raisin,1gl the piston valve and ,operatamlvacuurnline 34 being;- of the lusual constructlon. 'Here the two devices arelncor-A porated ln'a single-casing 35-carry1ng the vacuum tank 36`and the valve casingl 37. ,A `one-way lock'38, controlled by a key, is used, there beinga T-joint 39 in the vacuum line, one branch '40 leading to'the tank; and the i other branch 41 leading to )the lock. The

valve casing, is' connected through'tlie lock to the vacuum line and the piston valve hastwo portionsy 42 'and'v 43 controlling the main gasolene line 44 and the,carburcter line 33,'4

respectively. e l v In this form, while theengineis rainning, the lock 38 is closed andthe piston valve Vis in its lower positiondue to its weight, allowing the gasolene to flow lthroinqli both the main gasolene line and thecarburcter line. j When the lock "is turned opening the vacuum said Vacu'uin line and adapted to open same to theatmosphere in .one position, and a line to the 'valve casingthe vacuum in the casing raisesthe piston valve, closing both the mainV gasolcne line and the lineto Vthe '.30 carburetor; Any attempt to run the engine closes these two lines and thus no 'gasolcne can reachthe carbureter.

In F ig. 6 a form similar to Fig. 5, but i -with a slight modiications shown. In this form the lock isa three-wayloelcthe vacuum line 50 entering o neside, andin the normal running position, 'being connected to the 'VaCuumtank through the line 51. In the locked position the line, 5l is vented to the 40 atmosphere through the lock and the line 50 is connected to the valve 'casing throughihe pipe-52, thus raising` the' plunger and closing` the gasolene line and the' carburetor line, preventing the flow of g'asolcne In apparatus of the present type,- where the vacuum tank is already installed, the.

present device may be readily added, while 1t is, of course, understood that in new installations, it would .be preferable to mcor.-

.pol-ate the locking means directly With the vacuum tank. The key lock may be placed Y invany readily accessible position, lbut having the apertureslO :to the atmosphere placed in such a position that they are; relatively inaccessible to prevent plu, ;,'gingr the same.

As the vacuum li'ne controls the piston valve,

the latter operates automatically'to close the gasolene lines upon movementl of the key.

l. By. the use of the present apparatus any -gasoline system may be securely locked and a'c'arbureter may be shut oil from the gasolene supply. In any fuel syst/sm where' a carbureter supply line or main gasolene line is used, the line iscontrolled by the valve A. actuated by the vacuum line. The locky cona carburetor fuel line, of a -lock` con- I trois the vacuum line so `that the valve closes l the fuel line ports 1n the casing. Whe n the. car is stopped the engine may run `untll the fuel in the carburetor is exhausted, after which the car cannot be started until the lock .is turned to open the valve. The car, of

` in the'carbureterbefore the engine stops and becomes impossible. to start-- Other modcs of applyingthe principle of nly invention -may be employed instead of the one explained, change being made as regards the 1necl1anis1n` herein disclosed, provided the means stated by any of the follow'- ing claims or the equivalent of such stated incans be employed.

. I therefore particularly point out and distinctly claim as my invention Y l.
